Application filed January 28, 1901. Serial No. 45,065. \No model.)

To aZZ 20720777, it may concern.-

Be it known that I, BENJAMIN F. ROBIN- SON, a citizen of the United States, residing at Agricola, in the county of Tallapoosa and State of Alabama, have invented certain new and useful Improvements in Fertilizer-Distributers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to fertilizer-distributers, and has for its object the production of an improved appliance of this character which is adapted for attachment to a com mon" plow and which possess advantages in point of simplicity and durability of construction and efficiency in operation.

The nature of my invention willbe readily comprehended, reference being had to 'the following detailed description and to the accompanying drawings, in which Figure 1 is a perspective view of a fertilizerdistributer embodying my invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a side elevation of the same, certain of the parts being partly broken away.

Referring to the said drawings by letter, A denotes upright frame members, to the upper ends of which is pivoted a vibratory h'opper 13 and to the lower ends of which is secured a bolt a, forming the axle for a supporting-wheel D. The delivery-outlet b of the hopper is at the lower front side and is controlled by a slidable gate e to regulate the feed of the fertilizer. From the delivery-outlet b of the hopper extends a trough f, which is inclined downwardly and delivers into a distributing-nozzle g, secured to arms a, forminga part of the frame. The arms are rigidly secured to the uprights A, and a is a yoke also secured to the uprights and which may be made integral with the arms a. The lower rear end of the hopper is forcibly held against the yoke by a coiled spring h, which is attached to a hook h on the yoke and to a pin or screw 71 on the bottom of the hopper.

The wheel is provided at one side with an annular series of pins d d. On one side of the hopper is pivoted an arm 2', the lower end 1" of which is in the path of the pins d, and the upper end i engages any one of a series of teeth on a platej, secured to the upper end of the hopper. The arm 7; is in operation rigid with the hopper, and in the rotation of the wheel the lower end of the arm is engaged by the pins successively, with the result of vibrating the hopper and effecting the distribution of the fertilizer. The pivotal point of the arm is preferably near the lower end of the hopper, and said arm is movable thereon to bring its end 2" more or less into the path of the pins to vary the extent of vibrations of the hopper, the adjusted positions of the arm being maintained by the engagement of the upper end 2' with the teeth j. By this adjustment the distribution of the fertilizer can be readily controlled. lo denotes a wear-plate which is attached to the hopper at the point of contact with the yoke.

The distributer, as before stated, is adapted for attachment to the stock of a common plow and to this end is provided with upper straps and bolts ZZ, secured to the uprights, and with lower straps and bolts m m, secured to the axle-bolt c.

I claim as my invention 1. A fertilizer-distributor having a frame, a spring-held hopper pivoted to the frame, a wheel having an annular series of pins, and an arm on the hopper extending into the path of the pins to effect the rocking of the hopper against the action of the spring.

2. A fertilizer-distributer having a frame provided with means for attachment to a plow or the like, a vibratory hopper pivoted near its upper end to the frame and having its lower end spring-held against a stop on the frame, a wheel mounted in the frame and having an annular series of pins, an arm pivoted to the hopper and adapted to be adjusted to bring its lower end a greater or less extent into the path of the pins to vary the vibrations of the hopper, and means for main taining the adjusted position of the arm.

3. A fertilizer-distributer having a frame, a spring-held vibratory hopper pivoted to the frame, and provided at its lower end with an teeth on the hopper to be engaged by the leoutlet controlled by an adjustable gate, a ver to maintain its adjustment. :0 trough leading from the outlet, a nozzle sup- In testimony whereof I aflix my signature ported on the frame to reeeive the fertilizer in presence of two witnesses.
